Concrete with superhydrophobicity can protect it from being eroded by water and reduce accumulation of dust. Herein, a green and efficient method was proposed for fabricating hierarchical structures on concrete surfaces with superhydrophobicity by directly replicating micro-nano dendritic structures from superhydrophobic copper mesh to fresh concrete. Microstructures, chemical compositions and wettability of the as-fabricated concrete were characterized. Superhydrophobicity of the as-fabricated concrete was studied. Effect of water jet on the as-fabricated concrete was investigated. Wetting durability of the as-fabricated concrete were studied. Self-cleaning property was confirmed. It was found that owing to the successful replication of micro-nano dendritic structures and low surface energy stearic acid, the as-fabricated concrete displayed good superhydrophobicity, wetting durability and self-cleaning property.
